"So let's say you have some data that you want to protect and you need the convenience of having it on a portable drive. A standard portable hard drive just doesn't cut it. Sure, they are inexpensive, but you really need a level of security that just isn't found on those types of drives. Well, iStorage has something that can keep your data secure. How secure? How about Real-Time Military Grade AES-XTS 256-bit Full-Disk Hardware Encryption secure? Okay, maybe not everyone needs that level of security, but if you do, then the iStorage diskAsure Pro2 can do the job."
